Leo Durocher signed Official American League (Bobby Brown) baseball. Beckett Certificate of Authenticity (ball is stickered and has accompanying Beckett cert card with matching authentication number). Leo "the Lip" is the second winningest manager in National League history, managing the Brooklyn Dodgers, New York Giants, Chicago Cubs, and Houston Astros. He guided the Giants to the 1954 World Series - the last they would win before moving to San Francisco. In nearly a constant state of war with League commissioners and presidents, he was a strong supporter of Jackie Robinson, though his antics off the field saw him suspended for Robinson's debut season with the Dodgers. He passed away before his 1994 induction in the Baseball Hall of Fame, making his signature somewhat rarer.
